Trail at Budget Terminal

I realised that Singapore Changi Terminal 3 is different from the Budget Terminal. So I am writing this to correct my mistake. Sorry...! :P

This morning, I helped to conduct an educational trail at Changi Budget Terminal. Basically, it was a maths trail. I was happy to meet a number of familiar faces there. They were my ex-pupils. Most were happy to see me, but one kept avoiding me and even hid behind his classmate when he boarded the bus. Well, I would say he had gained some weight. :p
